SAFETY RAZOR BLADE Filed July 31, 1954 Elmo/rm Vzlmmi Mz'zmzZZzIPatented June 4, 1935 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to a safety razor blade and particularly one ofthe type adapted for use in the improved magazine razor blade holderfiled by me of even date herewith.

It is particularly aimed to provide a blade adapted for ejection fromthe razor or holder and especially through the lowering movement of anew blade to contact with the old or blade being discharged, andparticularly to provide such a construction as avoids the possibility ofthe cutting edge of the upper blade being damaged or marred by contactwith the lower blade.

The more specific objects and advantages will in part be pointed out orbecome apparent from a consideration of the description following takenin connection with accompanying drawing illustrating an operativeembodiment.

In said drawing Figure 1 is a view in front elevation illustrating apair of blades in the position they assume in the razor construction,when the lowermost blade is being ejected by the uppermost blade;

Figure 2 is a plan view of a stack of the blades;

Figure 3 is an enlarged front elevation of one of the blades;

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 3,and

Figure 5 is a cross sectional detail taken on the line 5-5 of Figure 3.

The razor blade made of any suitable metal or material is generally ofrectangular shape, being generally designated I and preferably beveledor sharpened at its cutting edge I I, from one side of the blade only.

Adjacent opposite ends of the blade, slots or holes I2 are providedtherethrough adapted to be engaged by holding elements of the holder orsafety razor construction in which it is used.

The upper edge proper of said blade has any suitable number of notchesl3, preferably a pair cut therein. Such notches are adapted to beengaged by the fingers in the safety razor construction, to hold theblade and aid in seating the same to operative position.

Since the fingers in instances where all of the notches l3 are alined ina stack of the blades, might engage and tend to feed more than one ofthe blades, such notches 13 of alternate blades in a stack, as shown inFigure 2, are disalined, the alternate blades thus limiting inwardmovement of the fingers and preventing engagement thereof with more thanone blade.

It is also a feature in the razor blade construction of the previouslymentioned application filed of even date herewith, to use the upperblade, to displace the lower blade, when the latter has become dull oris to be ejected. The upper blade is moved downwardly against the lowerblade, as in the relation of Figure 1, causing the lower blade to beejected. In order to prevent contact of the cutting edge of the upperblade with the lower blade, the lower corners of each blade are cut awayas at M and lugs l5 are provided adjacent opposite ends of each bladeextending above the upper edge. Such lugs l5 are higher than the heightof the cut away portions l4 and hence such cutting edges II are heldspaced from or out of engagement with the lower blade, when a pair of 15the blades are engaged as in Figure 1.

Various changes may be resorted to provided they fall within the spiritand scope of the invention.

I claim as my invention:

1. A blade of the class described having a notch in its upper edgeengageable by feeding and retaining means of a razor construction, lugsextending from the blade at opposite ends thereof, the blade at itscutting edge having notches 01' less depth than the length of said lugsfor the purpose specified.

2. A blade of the class described having a notch in its upper edgeengageable by feeding and retaining means of a razor construction, lugsextending from the blade at opposite ends thereof, the blade at itscutting edge having rectangular notches of less depth than the length ofsaid lugs, and slots in the blade adjacent opposite ends thereof for thepurpose specified, the inner side walls of said slots being transverselyalined with the transverse walls of said rectangular notches.

3. In a razor blade, a blade substantially rectangular in shape andhaving one edge sharpened, lugs extending rearwardly from the edgeopposite to the sharpened edge, and the sharpened edge of the bladeprovided with notches alined with the lugs aforesaid and less in depththan the length of said lugs for the purpose stated.

4. In a razor blade, a blade substantially rectangular in shape andhaving one edge sharpened, lugs extending rearwardly from the edgeopposite to the sharpened edge and at opposite ends of the blade, andthe ends of the sharpened edge of the blade provided with notches ofless depth than length of said lugs for the purpose stated.
